Background:  The aim of this study was to investigate the biomechanical properties of the cornea and their association with intraocular pressure (IOP), central corneal thickness (CCT) and the central corneal radius of curvature (Rc).

Methods:  Eighty‐three eyes were divided into two groups. The biomechanical properties of the cornea were measured in 63 normal eyes and in 20 post‐laser in situ keratomileusis (LASIK) eyes. The IOP, corneal hysteresis (CH) and corneal resistance factor (CRF) were measured by the Ocular Response Analyzer (ORA). The Rc and CCT were measured using the corneal topographer Medmont E‐300 and the Tomey SP‐100 Handy ultrasonic pachymeter. Other parameters measured by the ORA, such as TimeIn and TimeOut, were also studied.

Results:  A mean corneal hysteresis of 10.8-mmHg and CRF of 10.6-mmHg were recorded for the normal eyes. There was no significant …
